TOPIC: This looks like an Inspection, not Audit

This question from pmexamcoach.com looks like an Inspection to me but the correct answer is given as Quality Audit:
A series of approved changes have been made and your team is making sure that all of the approved changes are now in place and working as expected. They are engaged in what activity?

I found the following keywords can be used to differentiate Quality Audit vs. Inspection:
Audit is process oriented, inspection is product/deliverable oriented.
Audit is about finding best practices, inspection is to find issues.
Audit is in Manage Quality process, inspection is in Quality Control process

Also, Approved Change Requests from Integrated Change Control are 'fed' to Control Quality process, not Manage Quality process.
And Control Quality process utilizes Inspection, not Audit.

With these information, it looks like the question is asking about an Inspection.
What's your thought?
